Explaining match outcome in elite Australian Rules football using team performance indicators

The relationships between team performance indicators and match outcome have been examined in many team sports, however are limited in Australian Rules football. Using data from the 2013 and 2014 Australian Football League (AFL) regular seasons, this study assessed the ability of commonly reported discrete team performance indicators presented in their relative form (standardised against their opposition for a given match) to explain match outcome (Win/Loss). Logistic regression and decision tree (chi-squared automatic interaction detection (CHAID)) analyses both revealed relative differences between opposing teams for “kicks” and “goal conversion” as the most influential in explaining match outcome, with two models achieving 88.3% and 89.8% classification accuracies, respectively. Models incorporating a smaller performance indicator set displayed a slightly reduced ability to explain match outcome (81.0% and 81.5% for logistic regression and CHAID, respectively). However, both were fit to 2014 data with reduced error in comparison to the full models. Despite performance similarities across the two analysis approaches, the CHAID model revealed multiple winning performance indicator profiles, thereby increasing its comparative feasibility for use in the field. Coaches and analysts may find these results useful in informing strategy and game plan development in Australian Rules football, with the development of team-specific models recommended in future.

新疆经济发展的几个深层次问题分析

新疆经济发展的深层次问题，在于能否在工业上加速体制改革，实现信息化与工业化的对接，克服发展中的短腿问题。农业上能否从体制上解决农牧民“市民化”问题，以农村经济合作组织推进农业“新四化”。南北疆的共同富裕在于能否以“东联西出”实现“南北互动”，在积累中实现“互动发展”问题。向西发展的关键在于能否加入世界经济发展的潮流，实现可靠安全的“走出去”战略。

X marks the spot: Creating and managing a single service point to improve customer service and maximize resources

ABSTRACT

This article will describe how merging service points in an academic library is an opportunity to improve customer service and utilize staffing resources more efficiently. Combining service points provides libraries with the ability to create a more positive library experience for patrons by minimizing the ping-pong effect for assistance. The Access Services Department at the University of North Texas Libraries was charged with management of the circulation and reference services offered at the service desk. Streamlined planning and modernized management of the desk and its impact on customer service in a changing library environment will be discussed.     

Enhancing Teaching and Learning: Libraries and Open Educational Resources in the Classroom

Academic libraries continually adjust services to adapt to the ever-changing landscape in higher education. In response to the broken textbook market, libraries are becoming actively involved in the open educational resources (OER) movement. Although there is not a formal program in place, librarians at Utah State University explored a collaborative approach to integrate OER in faculty members' courses. One goal of the effort was to work closely with faculty to consider course objectives and learning outcomes when evaluating and incorporating OER. This article identifies a streamlined process for targeting courses most suited for OER adoption and outlines a process of collaborating with teaching faculty to integrate relevant OER. The paper includes a detailed workflow that other libraries can easily adapt to make OER part of their faculty outreach toolkit.
